IPC: B64C11/18
Filed: 1987-11-14
Abstract: A propulsor blade for an aircraft engine having counterrotating sets of blades, includes an airfoil section 310 and a metallic blade spar 300 interposed between opposed surfaces of the blade to which it is bonded to establish structural integrity of the blade. The metallic blade spar may include a root end (302) allowing attachment of the blade to the engine. The blade surfaces are formed by composite laminates (eg fibre reinforced resins - details disclosed) bonded together, and cavities 318, 320 may be provided to decrease the weight of the blade. The cavities may be filled with low-density foam. A nickel plate sheath 324 may be provided for protecting the leading edge of the blade and fasteners 500 to 504 may be provided for improving its structural integrity. The spar itself may be provided with weight reducing cavities and undercuts (Figs. 14, 15, 17 to 21) and balance weights may be provided (Fig. 12).

Title: Stacking arm
Inventor: WALKER ERWIN
IPC: B65G1/14
Filed: 1988-03-09
Abstract: A stacking arm for stacking store articles of approximately equal shape and size at mutual intervals has rotatably mounted pawl levers which in each case receive one store article and can be swivelled from a resting position, via a ready position, into a working position and back again. The stacking arm runs essentially horizontally and receives the store articles in an essentially vertical position. Every pawl lever has a stop surface which comes into engagement with the store article, the store article being horizontally fixed by the stop surface. The individual pawl levers are connected to one another by coupling links which, when one pawl lever is transferred from the ready position into the working position, bring the next pawl lever from its resting position into the ready position.

Title: Process for the aerobic fermentative hydrolysis, in particular composting, of organic substances and apparatus for carrying out this process
Inventor: HOFMANN HERMANN
IPC: C05F9/02
Filed: 1988-04-05
Abstract: A process serves for the aerobic fermentative hydrolysis, in particular composting, of organic substances (1) in a closed vessel (5). Fresh air is fed to the organic substances (1). The heat- and moisture-laden exhaust air is conducted off. In order to avoid the previously existing pollution, in particular odour pollution, the exhaust air is cooled so that the moisture condenses out (14). The exhaust air is then conducted off at ambient temperature and without moisture to the atmosphere. An apparatus for carrying out this process comprises a fermentation vessel (5) for receiving the organic substances (1) to be processed, having a fresh air feed and an exhaust air discharge for conducting off the heat- and moisture-laden exhaust air. The pollution, in particular odour pollution, of the atmosphere is avoided by the fermentation vessel (5) being closed on all sides and by a heat exchanger (9, 28) being provided, in which the heat of the exhaust air is given off to a heat transport medium, preferably the fresh air supplied, so that the moisture is condensed out (14) from the exhaust air (only one figure). <IMAGE>

Title: Device for determining the filling level of a coin-stack container arranged in a coin-operated machine
Inventor: GAUSELMANN PAUL
IPC: G07D1/00
Filed: 1989-01-25
Abstract: In known devices for determining the actual filling level of a coin-stack container, the coins located in the coin-stack container change a reactance which controls a converter forming a filling-level actual value. The recording and evaluation are relatively complicated, because the filling level of adjacent coin-stack containers also has to be taken into account. By means of the new device, the actual filling level of the coin-stack container is to be recorded in a simple way and in a manner uninfluenced by adjacent components. For this purpose, the weight of the coins located in the coin-stack containers is fed to an electromechanical converter, the output signal of which is fed to a counter indicating the filling level actual value.

Title: Securing device for anti-theft protection
Inventor: WEBER WOLFGANG
IPC: E05B13/00
Filed: 1989-03-01
Abstract: Securing device for anti-theft protection of vehicles, in particular ships (sports boats). To prevent theft or unauthorised use of ships, in particular sports boats, it is necessary to secure the steering system (rudder system). By virtue of the securing device it is possible to separate the connection in sports boats between the tiller/rudder wheel and the rudder shaft and hence to make it impossible to steer a boat. The locking or release of the securing device is made possible by a rotary ring through which a locking pin is moved and, as a result, the two main parts of the device, which are each fixedly connected to the tiller or to the rudder wheel and the rudder shaft, are connected or separated. The securing device can be locked against unauthorised use and against theft with an inserted cylinder lock.

Title: Rubber mounting to hold car exhaust pipe - comprising ring contg. reinforcing layer which runs round its centre and is corrugated between holding points so as to stretch under load
Inventor: BLOEDEL-PAWLIK JUERGEN
IPC: B60K13/04
Filed: 1989-11-14
Abstract: A rubber suspension member contg. reinforcement and partic. a mounting to hold the exhaust pipe on a car body, is basically annular in shape with two gripping areas fo retg. hooks set diametrically opposite each other. The incorporated reinforcement is corrugated at the parts which are subject to tension and lie between the gripping areas. The figure shows the prod. in the unstretched state. It is designed to hold an exhaust pipe by gripping parts (1,2) which engage suitable retg. hooks (3,4) of which one is attached to the car body and the other to the pipe. Round the rubber prod. it contains a high modulus annular reinforcing layer (5) at the centre of its thickness. Between the two gripping sections (1,2) this layer (5) is looped ot corrugated for about 1/6 of the circumference, elsewhere it has no such features. These loops etc. allow the layer (5) to stretch elastically. The layer (5) can be e.g. perforated to allow the rubber to pass through and bond better.

Patent DE-3937824-A1 (DE)
Title: Precision winder - has electronic control to prevent cop change when not empty or attempted threading up when cop tube is empty
Inventor: GRECKSCH HANS
IPC: B65H67/06
Filed: 1989-11-14
Abstract: On a precision winder which has automatic cop change and splicer, also having a yarn clearer before the cross winding mechanism, an electronic control system is introduced to supervisec the automatic action, which ensures the cop is not changed before it is empty, and that attempts are not made to thread up when there is insufficient yarn on the cop. The full cop (4) is advanced by the conveyor into a pneumatic jacket (17) with cylinders (13,19) to operate hinged sides, and air pressure jets (14-16) to force the yarn upwards past the anti-ballooner (43) into the acceptor unit (22) where it can be held, before being lifted (33) by the mobile pneumatic grip (25) to carry it across the tension (23) clearer (27) and shear unit . imilrly thg Qn frOm lhQ CrOS Windin mchanism is released, and brought down (36) to lie in the clearer (27) and shear unit (28). The clearer detects the  presence of the threads, with the static ability to  determine whether one, two or zero, and also thick and thin places in the yarn when running. When the yarn from the winding unit and from the cop are both detected by the clearer, the splicer (26) is brought into action, then the yarn (32) is released, and the splice is checked by the clearer, ends are cut away and removed by the suction unit (31). By means of the electronic control unit (42), the whole process is not repeated in the event of a break, or a removal of thick/thin place. The control is capable of carrying on from whichever section is still in place, dealing only with that which needs to be replenished. ADVANTAGE - There is a saving in time relative to each cop, as previous detectors always carry out the threading procedure before a cop change, and corresp. failure to detect a thread resulted in a cop change before the tube was empty.
